Adjusting alert preferences for messages, mentions, and activity within Microsoft Teams
Hi Ian,
Thanks for your post on the community forum. I'm Nik, an independent advisor here to assist you with this.
As per the description, I understand that you want to stop the email notification from for Teams activity. If so, you could turn off email notification by these steps:
Select profile pic icon > select settings > notifications > In Email section, Set "Missed activity emails" to "Off"(see screenshot).
Regards
Nik
